我正在努力使daal在我的项目中工作，现在遇到了以下错误-我正在努力理解它，甚至不确定从哪里开始调试。
我正在尝试复制此网站的代码：https://www.codeproject.com/Articles/1151606/Lightning-Fast-R-Machine-Learning-Algorithms，但在Windows 10中，并且具有以下软件（完全按照该网站的规定）：

答案 0 :(得分：0)
您需要使用Rcpp::as函数在R内部数据类型（SEXP）和普通C ++数据类型（int，string，...之间进行转换。 ）。当您将参数从R传递到C ++函数时，这是必需的。由于您在C ++代码中指定了参数，因此不需要此函数。以下应该在您的readCsv函数中起作用：
std::string fname = "C:/Users/Documents/BAJAJ.csv";
int k = 7;
或者，您可以坚持使用教程中从R传递这些参数的版本。
顺便说一句，您不需要将/加倍。只有\具有特殊含义，必须加倍引用以引用原义版本。
